In a distributed database, there are a number of databases that may be geographically distributed all over the world. A distributed DBMS manages the distributed database in a manner so that it appears as one single database to users. In the later part of the chapter, we go on to study ...
A users access rights refers to the privileges that the user is given regarding DBMS operations such as the rights to create a table, drop a table, add/delete/update tuples in a table or query upon the table. In distributed environments, since there are large number of tables and yet lar...

which were designed for achieving higher performance by exploiting parallelism in transaction workloads. Work on distributed DBMS was mainly motivated by the need to manage data for large organizations having different offices and subsidiaries but slow computer networks hamper...
DBMSindependent Distributed database architecture Distributed databases can be homogenous or heterogeneous. In a homogenous distributed database system, all the physical locations have the same underlying hardware and run the same operating systems and database applications. Homogenous distributed database sys...
All Oracle databases in a distributed database system use Oracle's networking software, Net8, to facilitate inter-database communication across a network. Just as Net8 connects clients and servers that operate on different computers of a network, it also allows database servers to communicate ...
